Abstract

The feasibility of an industrial-scale process for production of glycerol ethers by etherification of glycerol with iso-butene, catalyzed by homogeneous or heterogeneous acid catalyst in a reactive distillation column, is analyzed. Firstly, a conceptual design of the plant is developed containing the reaction section with a kinetic model for the reactive column and a black-box model for separation unit. The influence of i-butene excess on reaction selectivity and recycles magnitude is investigated. Analysis of the liquid-liquid equilibrium is used to design the separation section. Finally, a detailed design of the entire plant is performed using AspenPlus.
